Edderton Cross Slab is a Class III Pictish stone standing in the old graveyard of the village of Edderton, Easter Ross. The stone is of red sandstone. On the western side there is an undecorated but elegant celtic cross, the circles within its rings emphasised by being left in relief. On the eastern side there is another cross on the upper half, standing on a semi-circular base or arch, within which is a horseman in relief, with two further riders incised below.
